.MACHINE FOR ROLLING HORSESHOE-BLANK BARS.

SPECIFICATION forming part of Letters Patent No, 349,182, datedSeptember 14, 1886.

Application filed June 1], 185 .6.

Senial No. 204,854. (No model.)

To all whom, it mar concern.-

Be it known that I, JOHN H. SNYDER, of

Richmond, in the county of Henrico and State of Virginia, have inventeda new and useful Improvement in Machines for Rolling Horseshoe-Blanks,of which the following isa specification.

My invention relates to machines for rolling horseshoe'blanks, and is animprovement on the machine for which Letters Patent No. 194,934 weregranted to me September-4, 1877.

The present invention consistsin certain features of construction andcombinations of parts whereby the heel portions of the shoe are upset ornarrowed and thickened, as desired, and in other improvements, as willbe pointed out.

In the drawings, Figure 1 is a front elevation of my improvement. Fig. 2is a top plan view of same. Fig. 3 represents in detail the upper roll.Fig. 4 represents in detail the lower roll or hearing. Fig. 5 representsin detail the side roll, all of which will be described; and Fig. 6shows the blank after treatment by my machine. I

The base A and. housings B Z) are suitably formed to support the severalparts of the improvement. In the housings B b, I j ournal shafts O andD, which shafts are. by preference suitably geared to revolve together,as shown. On

the upper shaft, 0, just outside of housings B,

I form or fix a collar or flange, E, and the shaft On the extension e, Iplace the upper roll, F,which is provided with dies f, adapted to formin the blank the creases and indentations for the nail heads and holes,substantially as described in myformer patent. These dies are preferablyformed separate from the roll and secured thereto. This may be effectedby forming cavities or recesses in the body of the roll and fitting andsecuring the dies therein. A collar, G, is fitted on the extension cupagainst the upper roll, and bolts 9 are passed through said collar androll and into the collar E, thereby securing the roll F in place. Thelower roll, H, is fitted onto the end of shaft D, and removably securedthereto, as shown, so it maybe readily renewed when worn. This rollforms a back-bearing for the upper roll and the side roll, andpreferably has the pinion d formedintegralwith it. The rim of this rollis shaped in step form with the faces 1,2, and 3. The facelis arrangedin line below the collar G. the face 2 in line below the roll F, and theside 4.,connecting faces 2 and 3, forms the back wall ofa blankway 5, ofwhich the upper and lower rolls form, respectively, the top and bottom.

The vertical shaft I is journaled at its lower end in the base A and atits upper end in an overlapping frame, a. This shaft, as shown, is in acommon vertical plane with the shafts O and D, as is most clearly shownin Fig. 2. On this shaft is fixed a pinion, t, which meshes with thepinion d, by which means motion is given to shaft I, as is desired. Theside roll, J, is also fixed on the shaft I, and is arranged to form aside of the way 5. This roll is formed with a circular beveled face oredge, J, on its periphery, which gives a bevel finish to the thick orother edge of the blank, as will be readily understood, and the roll isalso provided with dicsj,which are preferablyinserted in recesses in theroll and project out beyond the same, as shown. upset the blank atproper intervals, and narrowand thicken the same at the parts which formwhen the blank is cut into lengths the heels of the shoes.

. In the construction shown the shanks of dies j are fitted intorecesses in the under side of the body of the roll, and, being suitablysecured, are braced by the pinion t, which fits snugly up against theunder side of the side roll, as shown in Fig. 1.

The collar G, which forms practicallya part of the upper roll, bearsagainst the upper surface of the side rolls at the edge of same, and theface 1 of the lower roll in turn bears against the lower surface ofsuchroll, and these parts G 1 serve to brace and give rigidity to the sideroll, as will be readily seen.

Where desired the upper roll may be provided with dies 6, for formingindentations 7 in the surface of the blank, to indicate where the sameshould be out.

It will be noticed that when the machine is given motion and a bar isfed into way 5, the upper roll serves to crease and indent same atproper intervals, and the side roll thickens it up at the heel portionsto form the desired These dies are fitted to I OL) blank. By arrangingthe rolls, side and top, to act at the same point, I avoid any drawingbetween the said rolls, as in my former patent, so there can be novariation in the relative location of thickened and creased portions ofthe blank incident to a variation in the drawing action, as isexperienced in the use of machines constructed according to my formerpatent aforesaid.

It will be noticed that the back-pressure in the upsetting ot' the blank.is borne against the side or edge 4, and through the same by the shaftD. To preserve the proper relation of the several rolls, I provide theshalt D with a disk, K, which bears alongside ot' a disk. L, on shaft 0.so that in case the shalt D should be pushed back any by the upsettingol' the blank the shat't C will be correspondiugly moved back, and therelation of the several rolls will be preserved.

Heretofore machines for rolling horseshoeblanks have been constructedwith two dierolls on horizontal shafts and one dieroll on a verticalshatt co-operating therewith, such die-rolls being constructed to moldand crease the bar and to thicken and upset the blank at its heelportion, and I do not broadly claim such construction as my invention;but,

Having thus described my invention, what I claim as new is- 1. Inamachinetorrollinghorseshoe-blanks,

the combination. with the shaft 0, provided with a roll, the shaft D,having a roll arranged to receive the side pressure in upsetting theblank. and the side roll, of the disks K and L, secured one on. each ofthe shal'ts O and 1'). whereby the relation of the rolls on said shat'tsmay be preserved, substantially as set forth.

2. In amachinet'orrollinghorseshoe-blanks, having upper and lower rollssupported on hm izontal shat'ts, the side roll, J, having a beveled faceor flange, J, and provided with dies for upsetting the blanks,substantially as set forth.

3. In a machine substantially as described, the combination, with theupper roll, F, a collar, G, arranged laterally to the said roll F, andthe side roll, 01' the lower roll havingt'accs 1 and 2 and a side orbearing edge, 4, all constructed and arranged substantially as setfortllf JOHN H. SNYDER.
